CLUTCH-PEDAL LOCK.

Application filed July 30,

To @ZZ wa-om z'' may concern:

Be it knownV that I, HURVY N. FULLER, a citizen of the UnitedStates, and a resident of Oto, in the county of lVoodbury and State of lowa, have invented certainnew and useful lmprovements in Clutch-Pedal Locks, of which the following is a specification.

My present inventionr has for its primary object the production of an improved lock mechanism for the clutch-controlling levers of suoli motor vehicles as the Ford, which employs the planetary type of transmission gearing. A further object of the invention is the production of a clutch-pedal lock, inexpensive in construction, thoroughly eflicient and dependable in operation, and readily applied to a Ford car. y

The above and other objects and advantages l successfully attain in the embodiment hereinafter described, defined in the appended claim and illustrated in the accompanying drawings'which form a part of this application, and of which:

F ig. l is a side elevation of the clutch-v pedal mechanism and associated parte of a Ford automobile, with the device of my invention applied thereto, parts y being shown in section, and Fig. 2 is a vertical section of the detent mechanism and associated parts.

While I have illustrated and hereinafter described a preferred embodiment of the invention, I would not be understood as being limited to such specific construction, for various alterations and modifications may be made in the details of construction and arrangement of parts herein disclosed without departing from the spirit and scope of the invention as defined` in the appended claim.

Referring now to the illustrations, 3 represents the dash of the vehicle, t thev footboard, under which is mounted a transmission case, 5, having fulcrumed thereon, as at 6, the usual clutch-pedal, 7, extending through a slot,.8, in the floor-board, d, and connected by a link, 9, with the lever, 10, carried by the clutch-shaft, 11.

The structure above set forth represents no part of my present invention, but serves to illustrate those parts of the vehicle with which the device of my invention is associated.

0n the lever, 7, I fulcrum, as at 12, a lever, 13, which extends forwardly and downengageable,

plate, 17, and

. wardly lthrough the slot, 8, and is providedon the under side of its front end portion with ratchet heei'h,y 14, the dash having a cut away portion, 15, toreceive the said toothed end portion, The said lever, 13, eX- tends a distance in the rear of the lever, 7, and is provided with a pedal portion, 16, suitably positioned for engagement, either by the toe or by the heel of the driver whenV his toe is on Vthe pedal portion of the lever, 7. To the front portion of the dash, immediately above the portion, 15, is secured the upper end of a rearwardly through the opening, 15, at approximately right angles to the lever, 13, and has its lower end secured to the dash by a suitable'bracket, 18. The plate, 17, is provided with a vertical slot, 19, through Awhich the toothed end portion of they lever, 14, freely reciprocates, the teeth14, being as at 20, withthe portion of the plate, 17, at the bottom of the slot therein.

n the vvrearface of the plate, 17, is a plate, 2 1, mounted to slide vertically onthe with a slot, 22,

provided the lever, 13, is free to reciprocate. The lower end portion of said plate, 21, is connected l by a retracting spring, 23, with the lower end portion of the plate, 17, which serves to hold `the plate, 21,- yieldably downwardly.

Above the lever, 113, vided with an arm, 24, through the slot, 19,v flexible link, 25, with crumed as at 27,-on a through Vwhich extending forwardly and connected by a a small lever, 26, ful-` bracket, 28, mounted on the rear of the dash, the said link, 25,

being free to slide through a suitable bushing129, inserted in an opening, 30, in the das Below the lever, 13, the plate, 21, is provided with a flat member, '31, so positioned that when the lever, 26, is depressed to draw the plate, upwardly, the part, 31, will prevent engagement of the teeth, 14, with the detent, 20.

The. lever, 26, isso constructed and the link, 25, so connected thereto that when the lever, 26, isdepressed vagainst the stop, 32, the link, 25, will be on a dead center with the lever fulcrum, 27, which prevents retro-- grade movement of the lever.

lt will now be clear that when the lever, 26, is in its upwardlyextendedor normal position and the driver forces the clutchpedal, 7, forwardly, the latter will be held piace, i7, which depends the plate, 21,-'is pro- .I

virtue o engagementv rearwardly therefrom,

cured to such part andfthrough which said a slotted vplate ee- Seeond lever extends, Said second lever being toothed .to engage the portion of the plate at the bottom of the Slot, and means movable downwardly and upwardly on the plate to accordingly place said second lever in -engageable .and nOn-engageable relation to the plate.

ln testimony whereof, l have lhereto set ymy hand this 12th day of July, 1920.

HUBVY N. FULLER.
